TABULATING DEVICE FOR TYPE-WRITING MACHINES- Specification of Letters Patent.

Patented June 25, 1907.

7 Application filed May 11, 1904. Serial 110.207.429-

.Be it knownthat I, EMILE LEOOULTRE, a citizen of the United States, residing at Alexandria, in the county of Alexandria, State of Virginia, have invented certain new and useful Improvements in Tabulating Devices for Type-Writing Machines, of which the following is a description, reference being had to the accompanying drawing, and to the letters and figures of referencemarked thereon. Y

My invention relates to tabulating devices for typewritingmachines, and isparticularly adapted for use in connection with typewriting machines of what is known as the Remington type.

In an application filed in the United States Patent' Ofiice, March 26, 1904, Serial'No. 200,114, I have shown and described a device ad'apted to be attachedto a typewriting machine, or used in connection therewith,

for tabulating work comprising a longitudi nally movable stop bar provided with a column stop, mountedon the frame of the machine, means for moving the stop bar longitudinally, and .t movable stop on the paper carriage normally out of line with the column stop and means for moving the movable stop into position to engage the column stop.

My present invention is primarily designed as an improvement on the invention shown and described in the application referred to and is designed to avoid the necessity of moving the stop carried by the carriage into and out of position to engage the column stop.

The invention is, however, applicable to other forms of'tabulating devices, than that shown and described in my application referred to.

With this object in view, my invention consists in providing the stop carried by the carriage with a flexible end section normally in line with the column stop and adapted to normally yield in passing a column stop, and

means for so locking the flexible end section whendesired, that it will serve to stop the, b

carriage when it comes against a column stop, as hereinafter described and claimed.

,1 Referring to the drawings, Figure 1 is'a top plan view of a typewriting machinehaving my improvement appliedto it, Figs. 2 and -3 are: side views of the typewritingjmachine taken from opposite s idesfFig. 4' is aside view partly in sectidn showing the stop cardirections.

Fig. 6 is a detail plan view showing the arm- 16 and its engagement with the tabulating stop bar.

Referring to the parts by reference numerals 1 indicates the frame of a typewriting machine of the Remington type; 2 indicates one of the printing keys; 3 indicates the paper carriage; 4 indicates the guiderod on which the carriage reciprocates'; 5 indicates the pinion of the escapement mechanism; and 6 the rack bar carried by the carriage and adapted to be raised out of'engagement with the pinion 5; 7 indicates the rearwardly extending arm connected with the rack arranged to come in contact With the marginal stops carried by the stop bar; 8 indicates lugs extending upward from the top plate of the machine supporting the stop bar and guide rod.

The constructid'n so far described is the ordinary construction commonly found in typewriting machines of the Remington type.

Instead of the means ordinarily employed for holding the journals of the guide rod in position on the keys 8, I employ brackets 10 having in their upper ends bearings 1 l in which is mounted a tabulating stop bar 12. This bar is shown as a notched bar of ordinary form adapted to receive column stops 13, but may be of any desired construction adapted to carry the column stop. The rearwardly extending arm 7 carries an extension 15 preferably having its end bent over as indicated at 15. Secured to the rear bar of the carriage is an arm 16 having an end section 17 flexibly connected to it preferably by a hinge joint 18, so constructed that the end section may swing freely in both On the side of the arm 16 is a locking device 19 oomprisin end of its head 1'9 normally forward ofthe hinge joint 18and adapted when operated to e swung rearward. against the flexible end section 17 to prevent the latter from swinging in its hinge joint.

This locking device.

. an arm pivoted at 19 to the arm 16and aving the rear is preferablycarried on the right hand side of the arm16 and is held against the arm 16 by a bar secured to the arm 16, bet een which and the arm, the head of the lodking device moves freel The locking device 19 has arearwardly ex-' 55 the to be depressed, pressing downward the end.

I (It with the column stops,

tendingatm 21 preferably having its end bent over as shown at 21. A spring 22 secured at one end to the arm 16 and at its free end bearing against the rearwardly extending arm 21 serves to hold the locking device 19 normally in retracted position so as to per mit the end section 17 to swing freely on its hinge joint 18-.

When the locking device is in retraotedposition the end section 17 will, as the carriage is moved across the machine, come in contact but by. reason of its flexible connection with the arm 16 it will yield to the right or left' according to the direction of movement of the carriage and will i not cause the carriage to be stopped. -Dement-isarrested bycontact of the end section 1'7with a column stop.

The depressionof the arm 21 and the extension is simultaneously effected by means-of a rod 24 carried'by arms 25 and sides of the frame 1. .30 indicates a series of 26 pivoted to the brackets 10. The arm 26 has a forwarclextension 26 to which is connected the upper. end of a link 27 the lower end of which is connected to a bar 27 extend ing across the machine and pivotally con nected at its ends to clamps 29'secured to the keys preferably arranged above andto the rear of the regular ke board and pivoted on a shaft 31' carried by camps 32 secured to the side of the frame of the machineand held in normal position by springs 33 secured to a bar 34.- carriedby clam s '35 secured to the frame of the machine) lie-key levers of the keys 30 are arranged to fitbetween the key levers of the keys 2 and their rear ends 31 are inposition to strike against and lift the bar 27. When operated these keys are also preferably arranged to operate a differential mechanism for shifting the rod which carries the column-stops longitudinally as described in my application above referred to.

On the operation of one of the differential keys the bar 27 will be raised and through link 27" andarm 26' will cause the rod 24 of the extension 15 to release the carriage and simultaneously pressing down the end of "the arm 21 to cause the locking device to engage the end section 17 to hold'it rigid with the arm 16 so as to cause the carriage to be stopped as the end of the end section 17 comes in contactwitha column stop. On

the release of thedrey '30 the spring 22 will reedfor use 1n I V operated tabulating machine, such as de- "turn the locking device to inoperative position permitting the end section 17 to swing to permit'the carriageto pass the column stop. Any convenient means may be provided for yieldingly holding the-end section 17 inline with the arm 16 such as a pair of light s rings 17 arranged one on one side and the ot ier on the opposite side of the arm 16 and any equivalent means of locking the flexible portion of the yielding stop may be employed in place of the means illustrated. I

While my iiivention is particularly intenclconnection with a differentially scribed in my application before referred to, it will be understood, that it maybe used in connection with tabulating devices which are not diiferentially operated; and also that it -may be employed in connection with stop members differently illustrated. I

The essential feature of my invention is to provide a tabulating mechanism of a type,- writing machine having two co-operative stops, said stops being normally inoperative but one of said stops b ing normally in the path of the other, with means forrendering arranged from those said. stops operative to arrest the carriage.
